Religious people always quote the same scripture over and over to try and discredit the power of the Spirit flowing through the believer. They quote Matthew 7:22-23 as if it applies to every believer who is operating in the power of God.
Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles?’ Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’ - Matthew 7:22-23
No doubt, this scripture will apply to many people who get results supernaturally, but it doesn't apply to everyone the way many religious people think. In fact, there are far more scripture verses that identify the one operating in power as a real believer. Since this is a quick to read blog, I'll just quote one portion of scripture, but if you do an in depth search, you'll see that I'm correct in saying there are many verses that define the true believer as one operating in power.
For we know, brothers and sisters loved by God, that he has chosen you, because our gospel came to you not simply with words but also with power, with the Holy Spirit and deep conviction. - 1Thessalonians 1:4-5
